"With or without religion.." Quote. Is Weinberg wrong?

[John V]

“With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.”

Just curious about this. I have had multiple arguments where I use this, although it is argued back that;

"Although not in the name of atheism, secular people can do wrong acts too" and "Good people do evil acts as well, so what's your point?"

What do people think about these counter arguments?

None of the arguments are worth a thing until you define good person, evil person, good thing, and evil thing. When you do that, the initial argument tends to fall apart.

Also the converse is missing from the initial argument, i.e., can relgion also cause evil people to do good things?

In the end this argument is catchy but has no real merit.
